Hello from "Jonesy".  One of you _not_ using Gmail or other email
systems that do not check for a valid DKIM-Signature and SPF record,
should re-forward this from _your_ email account to the list for others
to see.

The is re-emailing all subscribed incoming
emails to the user list.  Each of those emails _claims_ to be From: the
original sender.  But, when Gmail (or whoever) asks if the original
sender (e.g. Jonesy <trinity@...> ) is authorized to send via that
MTA, the answer is "NO".  Of course not.  I have no user account there.

The problem has been solved by many of the re-mailers/email reflectors.
For instance, one of the ham radio reflectors (called "rover") I belong
to now construct the From:
	From: Jonesy W3DHJ via Rover <rover@...>

Ergo, when gmail asks if rover@... is a permitted sender at, the answer is "YES".

Andrew Young's answer to the problem:
  "4. Use a different mail list backend"
is the correct answer.

For a little light reading on the matter:

As for its purpose, it SURE cuts down on the spam coming from botnets
with forged From: headers -- _if_ the forged domain supports DKIM.
And, my email server supports DKIM.

And, OBTW, gee whiz, I did not know that konqueror could use sftp://.
I started using fish:// back on Red Hat 6.2 at the turn of the century,
and never thought there would be anything new for ssh in konqueror.
Thanks for updating my Very Old (mis)understanding!!  :-)
